I recently purchased a 2005 People 150 and I wasn't sure what maintenance was performed on it, so I decided to replace the spark plug, air filter, engine oil and gear oil. My question concerns the gear oil. The manual says to fill with .18 L (= 180 ml). I put about that much in and it did not reach the top of the fill hole. So, I continued to fill it. I stopped after putting about 450 ml in and it still does not drain out the fill hole. Should I put more in until I reach the top of the fill hole? Anyone else experience this with a 150 or other Kymco scoooter? Thanks!

How do you think the manufacturer arrived at 180ml as full for the hub?? Because they designed it!!!
Drain the unit completely and refill will only 180ml. Or you will blow out a seal or worse..

I'm with olbull all the way! I'd hate to see you changing the oil on a car. Fill up to the top of the hole?
Sorry, just kidding. ::) Get that excess out ASAP. A seal is cheap, but the labor is a killer.

Alright guys, thanks for your replys, but here is where I am confused. When checking the gear oil level, the manual says to make sure it is up to the lower edge of the fill hole. However, 180 ml did not get me anywhere near the lower edge of the fill hole. I even took if for a ride to heat the gear oil up, thinking it would expand somewhat. But the fluid still was not at the lower edge of the fill hole. Could this be another example where the manual is wrong? I've found several contradictions in the manual already. When I fill the gear oil on the lower unit of my outboard, the manual says to fill until it comes out the fill hole and then put the bolt back in. So, it makes me wonder if the 180 ml is right.

Now I'm confused as well. Found the service manual on-line and it says exactly the same thing. >:(

The part about filling it is right at the bottom of the page.
How much came out when you drained it?
-
I first drained my engine oil and then drained the gear oil into the same container, so hard telling how much came out. Although, I would guess it was more than 180 ml, which is about 3/4 cup. I added some more gear oil today to see when it would actually start draining out the fill hole. Judging by what is left in the oil bottle and accounting for spillage, I'm guessing it took about 700 ml of gear oil!!!

180ml is .18 litre which is 6.084 oz. which is approx 3/4 of a cup. (cup being 8oz.) So this sounds like the amount you put in.HOWEVER the book also says "check the oil level from the oil check bolt hole and add the specified oil (type) to the proper level if the oil level is low.". This on level ground on the center stand. How else would you be able to check if it is low (no dip stick) If the factory only put in a small amount there would be no way to know how much to add .But I can't guess how you got 700ml in there. My P-250 lists .18litre (180ml same thing). Mine took about .266ml (9oz.)to be at the bottom of the check hole.Filling to the check hole is kind of a standard set up, on motorcycle rear drive units and on car rear axles, and manual transmissions/transaxles-oil to the bottom of the check hole. But I do wonder if the scooter was on level ground and NOT on the center stand, I bet the oil level would be closer to the listed 180ml/.18liter amount. I might try this next oil change, just to see. Also if any one is interested to convert Milliters to ounces(US fluid) -multiply the amount of milliters times .0338 to equal oz.---( or) liters times 33.81402 equals oz. Looking at my final drive unit the fluid may be taking up 1/4 to 1/3 of the total capacity/area. If you put in .18l I suspect it would be fine because gear oil climbs the gears when moving, and crawls along shafts. Just for the record my wife's Piaggio 150 rear drive unit oil amount was exactly the amount the manual listed when it ran out the check/fill hole.

Or you could just use the lazy man's way (Read my way. ;D) and just go here:

I use it so much that it's bookmarked. ;)

The scooter was on level ground and was up on the center stand when the oil was added. So, I'm just wondering if this was another error made in the translation of the owner's manual. :-\

A translation error is not completely impossible. I suggest you contact Kymco USA and inquire.

Please let us know what you find out. I'd also be interested in knowing how they treat you. Speed of response, how polite are they. etc. since I set great store in quality of service after the sale.

OK,
I emailed them. We'll see how long it takes them to respond. Unfortunately, their track record is not that great. I left a phone message with them about two weeks ago concerning another question I had and I have still not heard back from them. We'll give them another chance.........

Looks like they answer emails a lot quicker than they return phone messages ;D. I received a reply this morning from Steven Oliver of Kymco USA. He said, "The correct amount is .18 liters. If the unit is driven much with the oil level filled to the fill hole, the venting system for the gear box will start to draw some oil into the air filter box and will then start to drip out. This causes no damage to the unit but does make a big mess. Please drain your gear oil and refill with .18 liters."
So, I drained the .70 liters and filled with the proper amount. Bottom line: disregard the part in the manual that says the gear oil should be level with the bottom of the fill hole (this would result in exceeding the proper amount by more than .50 liter!). Between gear oil changes there appears to be no easy way to check if you have lost any fluid. The only sure way would be to drain and measure it!

Good info. Glad we got that settled. ;D
While we're on the subject;
Don't know if I've mentioned it before, but the easy way to fill the final drive is to go to a ranch or feed and grain store and get a large syringe (They use them on livestock.) and a piece of plastic tubing that will fit firmly over the tip. No spill, no waste and if you get a large enough one it makes an easy way to measure the amount you put in since they are accurately graduated in milliliters or cc's. ;)

Thanks for the tip OldGuy!
-
Hey! I learned something here too. This is a first as far as I'm concerned.Why bother to call it a check hole?, just put a threaded bolt holeup on top so it would be easier to put that .18 litre in!. Anyway I am glad you got an answer from Kymco. Thanks for sharing the info.

Hey! ---just to add to the confusion, I left the oil level in the rear drive unit filled to the bottom of the fill hole. I figured I would clean out the air filterbox when I started to see a film forming along the bottom seam- now about 600 highway miles later @ (50-65mph mostly) I don't have any oil from the rear drive unit vent hose going into the air box. The hose is not kinked or blocked- perhaps the synthetic oil I used does not foam or aeriate. I will check the air filter and box every 100 miles or so, but I think if it was going to happen it already would have, don't get me wrong I'm not trying to prove anything to anyone out there. I do R&D work at my work and some times I need to see what happens, as long as it's not dangerous or going to ruin anything (of my own anyway) .I do agree that the 180ml is the correct amount that should be used, and maybe that takes into account the different oil types, ambient temperature, unit temperature,oil temperature, expansion ,etc. But if I do not experiance any problems ,I like the idea of having an additional amount of oil in the drive unit (226ml vs 180ml). My P-250 is the "S" model 2008, although the rear unit looks the same as previous year models.?????
